Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3.

y - 2 = -3(x + 7)

y + 7 = -3(x - 2)

y + 2 = -3(x - 7)

y - 7 = -3(x + 2)

My answer is y - 7 = -3(x + 2)

Am I right? :)

you mixed up x and y

johnweldon1993 · Answer

y - y1 = m(x - x1) remember?

(7 , -2)
(x     y)

try it again...

anonymous · Answer

y - 2 = -3(x + 7)

johnweldon1993 · Answer

Remember your 'y' is a negative number...so if you have

y - y1 = m(x - x1)

y - (-2)...this becomes...?

anonymous · Answer

Oh yea!! Thats right, so it would be y + 2 = -3(x - 7)
